By Patricia Zengerle WASHINGTON (Reuters) - U.S. President Barack Obama will propose to Congress on Wednesday a new three-year authorization for the use of force against Islamic State with limits on U.S. combat troops' involvement, lawmakers and congressional aides said. Obama has defended his authority to lead an international coalition against Islamic State since Aug. 8 when U.S. fighter jets began attacking the jihadists in Iraq. But he has faced criticism for failing to seek the backing of Congress, where some accuse him of breaching his constitutional authority. Facing pressure to let lawmakers weigh in on an issue as important as the deployment of troops and chastened by elections that handed power in Congress to Republicans, he said in November he would request formal authorization for the use of military force (AUMF). An outline of that request, expected to be handed to Congress on Wednesday, could stir debate over how U.S. troops should be deployed and the extent of U.S. engagement in Iraq and Syria. The proposal would allow the use of special forces and advisors for defensive purposes but bar "enduring offensive ground forces," lawmakers and aides said. It would not, however, set geographic limits for the campaign against the group. Until now, Obama has justified U.S. air strikes in Iraq and Syria under a 2001 authorization passed after the Sept. 11 attacks and a 2002 authorization used by President George W. Bush in the Iraq war. The new proposal would repeal the 2002 authorization but leave in place the 2001 AUMF, which has been invoked by the White House to carry out drone and missile strikes against suspected al Qaeda militants in Yemen and Somalia. VOTE IN MARCH? Fueled by outrage over the death of aid worker Kayla Mueller, the last-known U.S. hostage held by Islamic State militants, as well as the slayings of journalists and a Jordanian pilot, lawmakers said they planned quick hearings on the authorization, and a vote within weeks of Congress' return from a Feb. 16-20 recess. Both Republicans and Democrats said there had been unusually close consultations between the administration and Capitol Hill on the authorization. Many of Obama's fellow Democrats, war-weary after more than a dozen years of fighting in Afghanistan and Iraq, say they will oppose any AUMF that includes "boots on the ground." Obama's opposition to the Iraq War helped propel him to victory in the 2008 campaign and bringing troops home from Iraq and Afghanistan has been a focus of his presidency. "I worry that this AUMF gives the ability for the next president to put ground troops back into the Middle East," said Senator Chris Murphy, adding that that would be a sticking point for himself and many other Democrats. Some hawkish Republicans oppose restrictions on military commanders such as a ban on ground troops. Others are calling for a more extensive authorization allowing U.S. forces to challenge President Bashar al-Assad of Syria, where a four-year-long civil war has fueled the rise of the Islamic State group. "If the authorization doesn't let us counter Assad's air power, I think it will fail," said Senator Lindsey Graham, a leading Republican foreign policy voice. The White House has declined to discuss the specific time frame or details of its planned AUMF.
